thanks

Thanks Another issue. I've only been working on individual 'components' of files to this point. One of these files typically has 9 or 10 components, all (essentially) similarly structured. Say I have a starting and an end point for all the components (start, end) and all the data is between...

Kevin I didn't explain the situation clearly enough, Sorry. When I say the array has a single element I mean that all of the data is in a single cell (all in cell zero). Your code does essentially the same thing. (size is 0; length is 1). What I need is for this data, broken by newline, to...

Almost. This is an incredible savings for me as the following code allows me to just grab all these lines as they are (given that I know the number of columns, once I know the length of the array, I can then move each column to an individual array): $data_file = "retestfile.txt"; # Open the...

That does the trick. Thanks

I need to pull all that data. Trying to figure out how to correctly use /s to span newlines. Once I do, I'll be able to pull the first set of data and I'll be on my way. Help me out, Kevin The line before the 2 (the first row in the sample) ends with "Comments \n" so why doesn't the...

I should've taken your advice earlier. Here's an abbreviated sample of the data I want to match --in this part of the file, it's multiple lines. I don't know before hand how many there are in each set until I parse the first set. The format of these sets is consistent, however. I've indicated...

Kevin I appreciate your help. All I really need at this point is the precise syntax for setting a range (starting pattern to end pattern) from which I can then test and extract data and stop; be it a WHILE, FOR or IF loop. This is a file that will, for the most part, be consistent. I need to...

I'm trying to parse a file that has similar data in different sections; thus I need to set limiting conditions or there will be overmatching. Problem is I can figure out the exact syntax. I've read a file into an array and am looping through each line of the array. I want to use a WHILE or...

I've created a linespoints graph with the array values plotted as points in the graph. Now, the show_values option, if set, would also print the numeric values of those points on the graph (at those points). My question: is there any way I would be able to print values other than the original...

figured it out: I was pushing into an array reference, which the function will not accept

looking for help in passing an array to the GD::GRAPH function $graph->set_legend(@legend_keys); passing the array as shown returns pointers to memory addresses. for my $k ( 0 .. $#legends_keys) { # size $graph->set_legend (@{$legends_keys[$k]}); } returns ONLY the last value (at...

1)In the documentation, when discussing the array of data for the chart, it states that "If you don't have a value for a point in a certain dataset, you can use undef, and the point will be skipped." Well, in fact, the point is not skipped but rather reverts to the lowest possible value. Can...

I realize that, that's why I've started with '0' in the heading. Here's what I want, more specifically: to loop through the array comparing 2 columns concurrently if I wanted to work with columns 1,3 first run through then columns 2,4 2nd run through, etc. how would I write the for loop...

I want to be able to move through the columns of a dynamic (size varies --nothing constant) 2 dimensional array, making calculations and then changes to the values. The colums would be accessed as pairs. for example 0 1 2 3 4 5 6 7 ... a 123 000...
